9 Claims.

This invention relates to a device for feeding paper inserts into insetsin can covers.

An object of the invention is to provide a device of simple constructionwhich will effectively feed paper inserts into can covers.

Another object of the invention is to provide a device which is capableof operating at a high rate of speed in an economical and efiicientmanner.

A further object of the invention is to provide a means of insertingadvertising matter in the form of paper booklets, cards or metal discsinto insets in can covers or into other articles or packages havinginsets in their outer surfaces.

There are various machines known to the art which are capable ofperforming the functions of the machine of this invention. These devices, however, are generally of an elaborate nature, containing manymoving parts which necessarily involves a high initial cost and asimilar cost of operation. Moreover, these machines are capable offeeding approximately sixty inserts per minute into can covers.

Our invention is of simple construction and is capable of feedingapproximately one-hundred and fifty inserts per minute into can coversor packages. The machine as here set forth performs two functions;first, a reciprocating arm engages and moves an insert from a stack, anddeposits said insert upon an inset in a can cover and, secondly, arotary inserting device then presses the insert into the inset.

The embodiment of our invention consists of a can conveyor in the formof a continuous chain l2 having equally spaced lugs l3 which form seatsfor the cans l4. The chain is driven over the conveyor structure l5 anda supporting table I6 by means of a gear I! driven by a shaft l8. Thisshaft is driven by a sprocket I9 and chain 29 from reduction gearing 2|.A motor 22 employing commercial electric current drives the reductiongearing through shaft 23 and flexible coupling 24.

An intermittent clutch 25 is driven from the reduction gearing by meansof chain 26 and 5 sprockets 21 and 28. The clutch is positioned on ashaft 29 held in bearings 30 which are mounted on standards 3|. Adriving clutch disc 32 carrying a lug 33 is made integral with thesprocket 28; both members running free on shaft 29. A driven clutch disc34 fastened to the shaft 29 has a pin 35 outwardly urged by spring 359and controlled by a lever 36 (Fig. 4). The pin has an inset 369 at itsouter extremity to provide a clearance for the lug 33 when the pin isdepressed by lever 36. When the lever is withdrawn, the pin urgedoutwardly by the spring, contacts the lug on the driving disc. The leveris bolted to a rod 37, supported by and freely movable in a guide 38which is positioned on the standard 3|. The lower end of the rod isbolted to an arm 39 which carries a plate 40 normally held in the pathof the moving cans seated on the con veyor by a contraction spring 4|(Fig. 2).

Each can passing along the conveyor contacts the plate and moves thearm, thus imparting a rotary movement to the lever which releases thepin 35 and allows it to engage the lug 33 upon the driven disc 32.Rotary movement is thus imparted to the shaft 29 and the cam 42 which isfastened to its extremity. After the momentary contact with a can uponthe conveyor, the arm is returned to its normal position by action ofthe spring 41. This action also places the lever in a position toreceive and depress the pin 35 thus disengaging it from the lug on thedriving disc. The pin has also an offset 349 in its outer surface toengage an inset 330 in the upper surface of the lever, to precludemovement of the disc when it is not being driven by the disc 32. Thusthe clutch is synchronized with the moving cans so that the drivenclutch disc carrying the pin and driving the cam revolves once for eachcan, while the driving clutch disc makes one revolution to actuate theclutch and one free revolution for each space between the cans.

A link43 is fastened in a slot 44 in the cam by means of an adjustablelug 45. The link pivotally engages an inclined finger 46 riding in aninclined groove 41 upon the inclined table 48. The 50 finger iscontrolled by the cam 42 and reciprocated in the groove with eachactuation of the cam. A demountable knife 49 bolted to the top of thefinger has an inset 5D slightly less than the thickness of one of theinserts. The reciproeating finger carries the knife in a slot 5| underthe insert stacking base 52. The knife engages one of the inserts 53from the stack and carries it through aperture 54 and deposits it uponthe inset 55 in a can cover. A downwardly urged stop 56 allows but oneinsert to pass through the aperture 54, with each outward stroke of thefinger. Preferably our stacking device consists of two verticallyinclined bars positioned on the stacking base 52 (Fig. 3) and againstwhich the inserts 53 rest. When the insert stack is nearly exhausted itis only necessary to place additional inserts upon the stack toreplenish it. The insert stack can, therefore, be replenished from timeto time without necessitating the stopping of the entire mechanism thusproviding a continuous feed which is highly desirous in this type ofmachine.

The inclined position of the table 48 and the parts thereon allow aninsert, engaged by the knife 49, to move downwardly in an inclinedposition so that the lower edge of the insert is brought close to itsposition in the inset of the cover of a moving can before the knife iswithdrawn.

A rotary inserting means consisting of ashaft .56, a hub 51 positionedon the shaft having projecting arms 58 which carry circular cups 59 inwhich are. seated rubber cylinders 60 having an inset 6| in their outerfaces, is positioned on standards 62. This inserting means is driven bya sprocket .63 and a chain 64 connected to shaft '18 of the conveyormechanism. The rotary movement .of this inserting means is sosynchronized with the can conveying means that each rubber cylindercontacts an insert upon a can cover.. The rotary speed is somewhatfaster than .the can movement so as to allow the rubber cylinder to movethe insert directly over the inset and then press the insert into thecan cover.
